BOX-PILE FOR MAKING BAR-IRON.

SPECIFICATION forming part of Letters Patent No. 510,763, dated December 12, 1893.

Application filed August 7, 1893. Serial No. 482,600. (No model.) i

To all whom it may concern.-

Be it known that 1, JOHN B. BAUGH, a'citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Box-Piles for Making Bar- Iron; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a new and useful improvement in box-piles for making bariron, and consists in a certain construction of parts as hereinafter fully set forth,-the essential features of which being pointed out particularly in the claim.

The object of the invention is to provide a box-pile in which the construction of the box is such as to render it strong and rigid without exterior fastenings, enabling the filling of scrap-iron to be readily placed therein and retained perfectly in place, also preserving the form and exterior face of the pile, enabling it to be passed from the furnace directly to the finishing rolls, and producing an amalgamated bar of superior quality at comparatively small cost. This object is attained by the construction illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a pile made with my improved box or case. Fig. 2 is a like view with the cover removed. Fig. 3 is a perspective View of an end portion of the box, showing the connecting cross piece, withdrawn from the slots in the side pieces.

Referring to the letters of reference,Adesignates the sides of the box; B the bottom, and O the top thereof. These parts are formed of rolled plates of the requisite length, width and thickness, the edges of the top and bottom extending flush with the vertical face of the sides, so as to form a rectangular case the planes of whose various faces are free from projections. The ends of the opposed sides are provided with open slots on that are adapted to receive the metal cross-pieces D, which are forced into said slots and tie said sides together at each end holding them approximately parallel. To prepare a pile with this improved box or case, the sides so coupled,

are placed upon the base B, and the ends built up with suitable scrap-bars b, which are placed longitudinally within the ends of the case above and below the cross-pieces D, Y which serve to retain said end scrapsin place.

The central portion of the case is then filled with scrap iron E, as shown-in Fig. 2, and the top 0 placed thereon, thus completing, the pile as shown in Fig. 1, in which form it is placed in the furnace, and when suitably heated is passed directly to the finishing rolls, 65.

producing a laminated bar of superior quality. The manner of supporting the case of this pile is such that it is firmly held while being filled or built up and when placed in the furnace is prevented from falling down angular metal-case the planes of whose exteriorfaces are free from projections, the sides of which are provided at the ends with longitudinal open slots, the transverse metal cross pieces adapted to be received tightly in said slots and support said sides, the ends of 0 said cross pieces terminating flush with the outer face of the case and the central filling of scrap-iron.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN B. BAUGH.
